I'm not sure that OOP will suddenly "click". It took me a while to really get
it. Now it is second nature.
OO was heralded as the silver bullet of the 1990s. It is not, of course. Much
of it is over used and results in clumsy contrived code. Java suffers from
this, as you can only have objects in Java. C++, which also allows mixed
procedural / OO code, can be pretty horrible.
Python is a good one to start with because it is elegantly simple, and does
not force you to use OOP; you can happily mix in procedural code.
It does have some oddities, such as the ability to bind methods to instances
of objects, rather than the class. That is very weird if you come from a
statically typed language background.
The Python tutorial at http://docs.python.org/tut/tut.html is as good a place
to start as any. Don't worry too much about the OO stuff. It will come to
you.
In Python (one of the things it is criticised for) you pass around an
explicit "self" pointer ("this" in C++ etc.). This, in fact, makes it easier
to see what is going on in terms of classes.
What languages have you used before? And, as Tom asks, what are you trying to
do with it?
